Looks like you've got somebody's cobbled together mess to me. Not sure what that coolant tank and exchanger are off of, looks almost like something off of an older PERKINS diesel to me. And I also see the automotive style HEI distributor(marine versions NEVER came with a vacuum advance as it is never used in a boat). Unfortunately it is tough to find older engines that haven't been messed with after all these years.

Thanks Ferm . . . that's exactly the kind of feedback I was hoping for. Gonna cut it out of the boat and get the parts I need bell housing, mainfolds, controls, tabs. Do you think it's worth trying to use this motor? or just scrap it and start with a fresh block? and get a marine distributor. It's gonna be a winter project.

It may or may not. A lot depends on the condition of the inside of the block. I would say it would be worth getting it out and pulling the t-stat housing and block drains to see what the inside of the cooling system looks like. If that looks good then pull the valve covers and see what it looks like inside them. I will say that is not a marine engine, but a car engine dropped into a boat. It looks like a EDELBROCK performer intake(looks like performer cast into it in front of the distributor), the water pump is an early GM short pump(definitely not a marine pump), and that is an auto style carb as it still has the decal valve on it.

I think ferm nailed all the high points, looks like someone swapped in a truck motor. Pull teh long block, run compression test, and start looking for a donor motor with good parts
